ABSTRACT:
A manual positive locking device for doors of refrigerators, freezers and the like that do not have positive door locks such as typically used in motor homes, the locking device having an integral switch connected to an electrical alarm and adapted to be connected to the electrical system of the vehicle such that attempting to start the vehicle with the locking device in the unlocked condition will alert the operator of the unsecured condition. A rotatable T-shaped handle is provided that can be turned to a position that holds refrigerator doors in a tightly closed condition and in such position opens the contacts of the integral switch. The handle can be turned to a position clear of the doors and in such position closes the contacts of the integral switch and thus enables the alarm circuit for initiation when the vehicle ignition switch is turned on.
